After having my bunny for 6 months now she has started to become a little nibbler and has started to chew everything!!! She is a free roam bunny and has the whole flat to go around. She is litter trained and has a litter tray in the corner of my lounge which use to have a bathroom mat underneath to protect my carpet from hay/wee however she started to chew that and i had to take it away from her. I then decided to get another bath mat but a clear plastic on but she went and chewed that too and had to remove it immediately. I then bought a cat litter tray mat that is more thicker but still made of some sort of plastic. At first she didnt touch it for weeks but now she has started to chew it again!!! She's also decided to have a go at the carpet underneath the mat! I need a mat underneath to protect my carpet and to stop the litter (hay) spreading everywhere. Can anyone suggest or show me something i can buy which is suitable for my rabbit and something that she cannot chew through? I was thinking of a baking tray but there arent any big enough, im looking for something which is around 80cm x 50 cm as her litter tray is quite large!
